3 Claims. (Cl. 235.-133) This invention relates to an improvedauxiliary, or outboard, tens-transfer mechanism for a calculatingmachine of the Thomas-type, such as disclosed in US. Patent No.2,229,889, issued to Carl M. F. Friden on January 28, 1941.

Heretofore, in calculating machines having a shiftable accumulator, orregister, carriage in which a plurality of ordinally arranged registerwheels are mounted, certain of such wheels will be positioned to theright and/or left of the stationary portion of the machine in anyshiftable position of the carriage. Within the stationary portion of themachine, an ordinal selection mechanism, an acuating mechanism, and atens-transfer mechanism are located to effect registration of values inthose register wheels aligned with the selection mechanism. In order toeffect a tens-transfer in the register wheels positioned to the left ofthe selection mechanism, an auxiliary tenstransfer mechanism is providedand comprises a series of tens-transfer disks, one for each wheel, and acontrol means therefor. In a machine having a ten-order selectionmechanism, commonly referred to as a ten-bank machine, a tens-transferinto those register wheels aligned with the selection mechanism and intothe two next higher order wheels is under the control of thetens-transfer mechanism in the stationary portion of the machine. In thetype of calculating machine referred to and described herein, theordinal register wheels aligned with the selection mechanism, togetherwith the two next higher order wheels, will hereinafter be referred toas the inboard orders, while those wheels to the left thereof will bereferred to as the outboard orders.

Each of' the disks of the auxiliary tens-transfer mechanism is providedwith a peripheral notch which is adapted for engagement by acorresponding one of a series of ordinal actuator fingers secured'on anaxially adjustable shaft rockably mounted in the accumulator carriage.The actuator fingers are angularly offset in a staggered relationshipaxially of the shaft and become effective, during a subtractiveoperation and upon rocking of the shaft, to successively enter the notchin the disk associated with the lower outboard order wheel if the wheelregisters and the notch ineach disk associated with the adjacent higher'order wheels which register 0." Similarly, if during an additiveoperation each of the outboard order wheels register 9 and. atens-transfer is effected through the highest inboard order, theactuator fingers will enter the notch of the disks associated with theoutboard order wheels. Following the entry of the fingers into thenotches of the corresponding disks, theshaft is axially adjusted in onedirection'or the other to effect a simultaneous tens-transfer in alloutboard order accumulator wheels. As the carriage is shifted to theright, each of the auxiliary tens-transfer.- disks, upon movement of thedisk inboard of the machine, is axially, moved to an inactive positionout of'th e rotational plane of the corresponding actuator finger.

Heretofore, in auxiliary'tens-transfer mechanisms of this type, therockingof the actuator fingers was under the the active positioning ofall the. fingers. I

It is, therefore, an object of the present invention to nited StatesPatent provide an improved auxiliary tens-transfer mechanism for acalculating machine.

It is another object of the present invention to provide independentlyoperable tens-transfer actuator members in an auxiliary tens-transfermechanism for use in a calculating machine.

Another object of the present invention is to provide an improvedtens-transfer control mechanism for each outboard order of a calculatingmachine.

A further object of this invention is the provision, in a calculatingmachine, of an improved auxiliary tens-transfer control mechanism inwhich the independently operable actuators associated with the outboardorders are successively disabled when ordinally shifted inboard of themachine.

Still another object is to provide an improved auxiliary tens-transfermechanism for a calculating machine whereby a tens-transfer into theoutboard orders of the machine is controlled by the highest inboardorder irrespective of the ordinally shifted position of the carriage.

Further objects and advantages will become apparent from the followingdescription of a preferred embodiment of the present invention which isshown in the accompanying drawings in which:

The invention as described herein is preferably incorporated in acalculating machine of the Thomas-type, such as that shown in theabove-mentioned Friden patent, No. 2,229,889. vIt is not intended thatits use should be limited only to a machine of this construction, sinceit is evident that the underlying principles thereof may beadvantageously applied to other types of calculating machines.

The mechanism which is conventional in the machine of theabove-mentioned patent will not be described herein, unless necessary toprovide a more complete understanding of the mechanism of the presentinvention. The calculating machine to which the invention isparticularly adapted, generally includes a body in which the selecting,actuating, and tens-transfer mechanisms are mounted, and a shiftableaccumulator carriage, which also supports a part of the tens-transfermechanism.

In the preferred embodiment of our invention dis closed. herein, thebodyof the calculating machine includes a base (not shown) having acover 11 .(FIG. 1) and right and left side frame members 12 and 13,respectively, mounted thereon (FIG. 2). Between the respective sideframes 12 and 13 there is provided a plurality of transverse framemembers including a front bearing plate 14, a center bearing plate 15and a rear bearing plate 16 which serve to support various parts of theoperating mechanism referred to hereinafter.

The register carriage 20 (FIGS. 1, 3 and S) is mounted in a well-knownmanner for endwise shifting movement wihtin the framework of the machineand under the control of a conventional power-driven mechanism. Theshifting movement of the carriage in either direction may be selectivelycontrolled by a depression of one or the other of a pair of manuallyoperable shift keys 17 and 18, or may be automatically controlled bycertain function control mechanisms which are customarily provided inmachines of this character.

Provided within the carriage 20 is a plurality of ordinally arrangedaccumulator numeral wheel shafts 21, which shafts are suitablyjournalled in the carriage frame bar 22. At its upper end, each shaft 21carries a numeral wheel 23 having the digits from to 9 inscribedthereon, and at its lower end carries a ten-tooth gear 24. Each numeralwheel 23 is rotatable in either direction to register positive ornegative values and for this purpose, gear 24 (FIGS. 2 and 3) hasassociated therewith a pair of opposed bevel gears 28 and 29 formed onthe respective ends of spool 30, slidably and nonrotatably mounted onthe square selection shaft 31. At its ends each square shaft 31 issuitably journalled in the front plate 14 and the rear plate 16 andintermediate its ends in plate 15. The spools 3i? and associated gears28 and 29 are shiftable in either direction relative to thecorresponding gear 24 by a transversely extending plus-minus gate strap32 positioned between each pair of gears and supported at its ends bysimilar arms 33, which arms are secured on gate shaft 34 journalled forrocking movement in side frame members 12 and 13. Thus if the gate 32 isrocked (counter-clockwise in FIG. 3), the gears 28 will enmesh with thecorresponding accumulator gears 24 to effect an additive registration onthe numeral wheels 23. Conversely, if the gate is rocked clockwise, thegears 29 will enmesh with the corresponding accumulator gears 24 and asubtractive registration will be effected. The rocking of the gate 32may be selectively controlled in a well-known manner by the depressionof a plus key 35 or a minus key 36 (FIG. 1).

It can be seen from the above description that an increment of movementof a spool 30 will be transmitted to its associated accumulator wheel 23following the engagement of either of the gears 28 or 29 with thecorresponding gear 24. Means are provided in the various orders of themachine to determine the number of increments of such movement. For thispurpose, a plurality of numeral, or value, keys 38 is provided for eachorder of the machine (FIG. 1). The numeral keys 38 in each ordercooperate conventionally with a pair of differential value selectionslides 39 and 40 (FIG. 2), which are mounted for endwise shiftingmovement and are differentially set in accordance with the values of thedepressed value key. Selection slide 39 is associated with the numeralkeys 38, determining values from "6 to 9, and the slide 4%) isassociated with the numeral keys 38, determining values from 1 to 5. Attheir rearward ends, each of the selection slides 39 and 40 isoperatively connected to a pair of selection geras 41 and 42,respectively, which gears are slidably but nonrotatably mounted on thesquare shafts 31. Each selection gear 41 and 42 is rovided with tenteeth and is arranged to cooperate respectively with the teeth of thestepped tooth actuators 43 and 44. The square shafts 31 are ordinallyarranged longitudinally of the machine in accordance with the ordinalarrangement of the keys 38 and the register wheels 23. In each adjacentpair of the transversely spaced orders of the selection mechanism, thereis provided a single longitudinal actuator shaft 46 on which each pairof stepped tooth actuators 43 and 44 for the respective orders issecured. Accordingly, the square selection shafts 31 of each of theadjacent pair of orders are spaced to either side of, and above, theassociated actuator shaft 46 (FIG. 2). At its forward end, each of theactuator shafts 4-6 is journalled in the transverse bearing plate 14 andat its rearward end is journalled in the auxiliary crossframe member 47spaced from, and secured on, hearing plate 15. Adjacent the forward endthereof, each of the actuator shafts 46 carries a bevel gear 48 meshingwith a similar bevel gear 49 secured on the main drive shaft 50 whichextends transversely of the machine and is journalled in side framemembers 12 and 13.

In the embodiment shown, a conventional source of power is provided inthe form of an electric motor which serves through a well-knowncyclically operable clutch means to impart one rotation to the maindrive shaft 50 for each cycle of machine operation. Thus, for eachrotation of the main drive shaft 50, the actuator shafts 46 andcorresponding stepped tooth actuators 43 and 44 will receive a singlerotation to cause a registration of the number selected by the depressedvalue key, or keys, 38 in the associated accumulator register wheels 23.Each pair of stepped tooth actuators 43 and 44 is mounted in angularlyoffset relation on the corresponding actuator shaft 46 and also relativeto the stepped tooth actuators associated with the adjacent higherorder. The arrangement is such that the teeth of the actuators 43 and 44associated with the units order, i.e., the rightmost order in FIG. 2,become active first, followed by the teeth of the actuators 43 and 44associated with the tens order and the other orders in successionthereafter.

Conventional means are provided for preventing overthrow of the registernumeral wheels upon termination of an actuation thereof. For thispurpose, the stepped tooth actuators 43 and 44 of each pair of actuatorsare so positioned on the corresponding actuator shaft 46 that their lastactive teeth are in alignment, and the Geneva wheel 55 (FIG. 2) carriedby each square selection shaft 31 cooperates with the locking disk 56 onthe associated actuator shaft 46. Each Geneva wheel 55 has ten concavefaces, the actively positioned one of which is engaged by the associatedlocking disk 56 immediately following actuation of either gear 41 or 42by the last active tooth of the respective corresponding actuator 43 or44. Consequently, the associated shaft 31 and as sociated numeral wheel23 are positively locked against further rotation. Since this mechanismforms no part of the present invention, the foregoing description isbelieved to suffice. However, for a more complete disclosure, referenceis to be had to the aforementioned Patent No. 2,229,889.

Machines of the type presently being described are generally providedwith six actuator shafts 46 and twelve square shafts 31. The first fiveactuator shafts 46 (from the right in FIG. 2) carry the stepped toothactuators 43 and 44 cooperating with the respective pairs of adjacentshafts 31 associated with the ten orders of the selection mechanism tocontrol the registration of a value placed in the keyboard into theregister wheels 23. The leftmost actuator shaft 46 (FIG. 2) cooperateswith the remaining pair of square shafts 31 to control a tens-transferfrom the tenth order into the eleventh and twelfth orders of theaccumulator register. Thus, the twelfth order numeral wheel 23 (from theright-hand end of the accumulator carriage 20) is normally the highestorder wheel to receive a tens-transfer impulse from the conventionaltens-transfer mechanism, when the carriage is in its leftmost position.Hence as stated hereinbefore, inasmuch as the conventional tens-transfermechanism is mounted within the stationary portion of the machine and iscontained in the space existing between the right and left side framesof the machine, the first twelve orders of the register (FIG. 1) may beconsidered to be the inboard orders thereof when the register carriageis in the register may be considered to constitue the outboard orders ofthe register. 7

Generally, the tens-transfer mechanism associated with the selectionmechanism cooperates with the actuator shafts 4 6 in a well-known mannerand comprises tripping means associated with each numeral wheel, exceptthat of the highest order wheel, and is controlled by a lower orderwheel to enable a drive connection from a tenstransfer actuator to thenumeral Wheel of the next higher order, so that such next higher ordernumeral wheel receives one increment of movement when the lower order.numeral wheel passes from 9 to 0" or 0 to 9. The sign character of thetransferred increment is determined in the same manner as the signcharacter of the digitation, i.e., by the meshing engagement of thegears 28 or 2-9 of spools 30 with the corresponding gears 24.

To effect thetripping of a tens-transfer, each numeral wheel shaft 21(FIGS. 2 and 3) is pro-vided with a tenstransfer cam 60 positionedimmediately below the carriage frame bar 22. Each cam 60' cooperateswith the corresponding tripping, or tens-transfer, lever 61 pivotallymounted in the frame bar 22 by means of stud 62, which is secured to thetens-transfer lever 61 and is journalled in a bore (not shown) providedin the frame bar. The tens-transfer lever 61 has nose 63 positioned inthe path of the transfer cam 69 of one order, so that when the numeralwheel 23 passes from 9 to 0, or from 0 to 9, the nose 63 is engaged bythe cam 66 and the lever 61 is rocked in a counter-clockwise direction,as

viewed in FIG. 2. The limit of such movement is deter-' shafts 79, foradjacent ordersof the machine, is spaced closer together than thespacing between the orders, so that both shafts 79 of each pair lie inthe path of a single restoring cam 81. The earns 81 are successivelyoperative to restore each operatively positioned shaft 79 and associatedgear 69 to the inoperative position thereof following a tens-transferoperation in the corresponding order.

, A similar tens-transfer actuator construction is provided for allorders, including the two highest inboard orders, i.e., the eleventh andtwelfth orders of the machine, thereby enabling a tens-transfer intothese orders. It is to be noted in FIG. 2 that although there are twotens-transfer actuators 71 and 72 shown on the righthand actuator shaft46, only that actuator associated with the tens-transfer gear 69 in thetens-order is necessary, since mined by the engagement of the face ofthe nose 63 with i the next adjacent transfer lever 61. Each lever 61 isalso provided with arm 64 extending into the next higher order of themachine and normally engaging the lever 61 of the next order adjacentits pivot stud 62. The formedover ear 66 at the end of the extended arm64 (FIG. 2) lies between a pair of annular flanges 67 formed on hub 63of a tens-transfer gear 69. Hub 63 and gear 69 are slidably, butnonrotatably, mounted on the square shaft 31, so that rocking movementof the tens-transfer lever 61 by a lower order numeral wheel 23 resultsin shifting the hub 68 and gear 69 in the adjacent higher order,forwardly of the machine to position the gear 69 in operative relationwith respect to the tens-transfer actuator therefor. Single toothtens-transfer actuator 71 for tenstransfer gear 6% is spaced from, andsecured with, the

tens-transfer actuator 72 of the adjacent lower order by gears 69 ineither shifted position thereof, and associated with the maintainingmeans-is a restore cam which 00- operates with each pair of adjacenttens-transfer gears 69.

The rearmost annular flange 67 of each gear hub 68 extends betweenspaced annular flanges 78 of the. correfrom, and secured to, thecrossbar 47. Each shaft 79 is provided with two annular grooves forcooperation With a spring-urged ball detent mounted in the transversemember 80, all of which is conventional and is not shown.

, Y sponding stub shaft 79 which is slidablymounted in the "crossbar 47and auxiliary transverse member 80, spaced Thus, the shafts 79 andtransfer gears 69 are maintained the crossbar 47 into the path of therestore cam 81 integrally formed with, and arcuately offset from, therearmost tens-transfer actuator 72 of each pair of associatedtens-transfer actuators. As seen in FIG. 2, each pair of notens-transfer occurs in the units order. It will also be noted that thetens-transfer actuators 71 and 72 on each actuator shaft 46, as well asthe successive pairs of actuators 71 and 72 on adjacent actuator shafts46, are angularly displaced to provide for operation of the tenstransferactuators seriatim from the lowest, or tens, order to the highest order.

Briefly, assuming that a tens-transfer has been determined by shiftingtwo of the transfer gears 69 in adjacent orders to active position, thecorresponding tens-transfer actuators 71 and 72 will have rotated fromtheir full-cycle position to a position Where the rearward actuator 72is positioned to impart a one tenth rotation to the associated gear 69to enter the transferred increment into the corresponding numeral wheel.Subsequently, the other, or for- Ward, actuator 71 will become effectiveWith respect to its associated tens-transfer gear 69 to cause one-tenthof a rotation thereof and complete the tens-transfer into the associatednumeral Wheel. The forward actuator 71, in effect, trails behind therearward actuator 72 a suflicient angular distance to accommodate thesetting of the tens-transfer mechanism in the adjacent higher order bymovement of the gear 69 to active position if the transferred incrementplaced in the adjacent loWer order numeral w eel associated with thisgear 69 determines a tens-transfer operation into the next higher ordernumeral wheel.

Various auxiliary tens-transfer mechanisms have been used heretofore inmachines of the type described herein to complete a tens-transferoperation into the outboard orders of an accumulator register. One ofsuch mechanisms functions in a mannersomewhat similar to that of theinvention presently to be described. However, it has been found thatthere are several limitations in the application of this particularprior art mechanism, which limitations will become apparent during theprogression of the following brief description thereof.

In an eight-bank machine in which the prior art mechanism isincorporated, the main tens-transfer mechanism in the machine iseffective to cause a transferred increment into the two dialsin theregister that lie to the left of the keyboard, or selection mechanism.'The eight dials in the register which are aligned with the keyboardorders, together with the two dials to the left thereof, are commonlyreferred to as the inboard orders of the machine, while those ordinaldials to the left thereof are referred to as the outboard orders.

For the auxiliary tens-transfer mechanism associated with the outboardorders of the machine, a bail is mounted for endwise movement on a shaftsecured Within the accumulator carriage. Movement of the bail in onedirection or the other determines the sign character of the registrationin the accumulator dials and is under the carried by the bail shaftrockably mounted thereon and restrained'between the legs of the bail forendwise movement therewith.

A series of ordinarily arranged tens-transfer actuators are secured onthe quill shaft for cooperation with corresponding notched disksassociated with the outboard orders of the register. Each disk isslidably mounted on the corresponding dial shaft, including the tenthorder, or highest, inboard order dial shaft, and is normally urged to anactive position for cooperation with the associated tens-transferactuator. Within one face of each disk there are ten equiangularlyspaced recesses, nine of which are shallow, while the tenth is in theform of a notch in the periphery of the disk. The leading edge of thecam portion of each tens-transfer actuator is angularly offset relativeto the adjacent actuator, thereby forming a spiral axially of the quillshaft and the trailing edges of the cam portion of the actuators areaxially aligned. Thus, the cam portion of the actuator associated withthe highest inboard order is the broadest, while that associated withthe highest outboard order is the narrowest.

In prior art auxiliary tens-transfer apparatus, a torsion spring servesto rock the quill shaft and the tens-transfer actuators thereon so thatwith the carriage in its leftmost position and following the manualsetting of the bail and actuators for addition, the actuator associatedwith the highest inboard order and those associated with all higheroutboard orders will be rocked into the notch of the disk associatedwith the corresponding ordinal dials if these dials register 9.Conversely, if the auxiliary mechanism is first conditioned for asubtractive registration and the dials register 0, each of thetens-transfer actuators will be rocked into the notch in thecorresponding dials.

The rocking movement of the tens-transfer actuators is restrained by ablocking member which is rocked out of the way in timed relation to thedigitation phase of each machine operation, thereby enabling thefunction of the torsion spring. The blocking member also serves torestore the tens-transfer actuators at the end of the operation.Following the rocking of the actuators to active position, an incrementof rotation of the tenth, or highest, inboard order will serve to movethe quill shaft axially, thereby imparting an increment of rotation toeach of the higher outboard orders. If, during an additive orsubtractive operation a 9 or 0 is not registered in an outboard orderdial, the actuator associated with that order and the actuatorsassociated with the order dials to the left thereof will be blocked fromentry into the notch of the corresponding dials.

As each order dial with which the auxiliary tens-transfer mechanism isassociated is moved inboard of the machine, the corresponding disk isrendered inactive by movement thereof, out of the rotational plane ofthe associated actuator. The last dial to be moved inboard becomes thehighest inboard order dial and is effective to cause axial translationof the quill shaft when the dial passes from 9" to O, or O to 9, therebycausing an incremental rotation of the higher order dials with which theassociated actuators are engaged.

Prior art auxiliary tens-transfer mechanisms of the type described abovehave been found to be unsatisfactory when there are more than sixoutboard orders involved. Inasmuch as the rocking of the actuators isunder the control of the torsion spring, the angular displacementbetween the leading edge of adjacent actuators must be held to a minimumto assure the possible engagement of the highest order actuator into thenotch of the disk associated with the corresponding dial. For eachadditional actuator employed, the angular displacement between actuatorsbecomes even more critical, and with the addition of two or moreactuators, the rocking movement thereof by means of a torsion spring isimpractical. The space requirement negates the use of a torsion springof sufficient size to effect an engagement of the leftmost of eight ormore outboard order actuators with the corresponding ordinal disks. Theincreased angular rocking movement of the quill shaft necessary for theoperation of two or more additional actuators renders the rockablerestore bar for the actuators inoperative since, upon movement of theactuators to active position, the axially aligned depending portions ofthe actuators are moved to a position out of the arcual path of therestore bar. Because of the spatial limitation in the machine and theshifting movement of the carriage, the restore mechanism for theactuators of Well-known auxiliary tens-transfer devices is not adaptableto machines having eight or move effective outboard orders.

Considering the above-described prior art in view of the followingdetailed description of the present invention, it will be seen that thepresent invention is adapted to overcome many of the objectionablefeatures found in the prior art.

In order to extend the increment transfer from one order of the registerto the next higher order thereof beyond the twelfth, or highest, inboardorder numeral wheel 23, the machine shown and described herein isprovided with an auxiliary, or outboard, tens-transfer mechanism, whichenables tens-transfers to be effected throughout the entire capacity ofthe register.

When the register carriage 20 occupies its leftmost position, the main,or convention, tens-transfer mechanism, described hereinbefore, isadapted to effect an incremental transfer into the twelfth order numeralWheel 23. Assuming now that the numeral wheels 23 in the carriage 20register 0 and that the 1 value key 38 in the first, or units, ordinalrow of keys (FIG. 1) is d..- pressed, the tens-transfer phase of asubtractive machine operation is not terminated with an incrementaltransfer into the twelfth order dial, but is fully carried to all thehigher outboard order dials by means of an auxiliary tenstransfermechanism under the control of the twelfth, or highest, inboard orderdial.

The present invention for controll'ng a tenstransfer into each of apredetermined number of the outboard ordinal accumulator dials 23 in theregister carriage, utilizes a series of independently rockabletens-transfer bails, or actuators, 102, 1&3, 1&4, 1G5, 1&6, 1G7, 103,109 and 11%) (FIGS. 3, 4, 5, 6 and 7). All of these bails are adjacentlymounted in an ordinal arrangement on a rod, or shaft 111, supported forendwise movement in brackets 112 and 113 secured on the carriage frame22, by s'milar screws 114 and 115, respectively. The actuators N32 to11s, inclusive, cooperate respectively with the highest inboard, ortwelfth, order dial and the successive higher outboard order dials. Eachof the dial shafts 21 for these orders, i.e., the twelfth to thetwentieth order, inclusive, carries a disk 118 secured thereon, whichdisk has nine open-end recesses, or fdentations, 119 in the lower facethereof and a peripheral notch 129. The recesses 119 and notch 120 areequiangularly spaced and, in essence, form the teeth of a gear. In the Oregistering position of a dial 23, the notch 120 is to the right of thevertical center line, as seen in FIG. 6, whereas, in the 9 position of adial 23, the notch 12th is one tooth-space removed 'n a clockwisedirection.

Each of the tens-transfer bails 1. 92 to 11%, inclusive, is formed in asomewhat similar manner, having legs 121 and 122 disposed in a parallelplane at a right angle to a bar 123 at the respective ends thereof.

The arrangement of the bails is such that the leg 121 of a bailassociated with a higher order is contiguous w'th the leg 122 of thebail of the adjacent lower order, so that the leading edge of anupwardly extended lug 1.24 on each leg 121 is normally in engagementwith a formed-- over car 125 on the leg 12 2 of the adjacent lower orderbail, as seen in FIG. 6. Inasmuch as the bail 192 is the rightmost bail,the leg 121 thereof does not carry a lug 124. In addition to the lug124, the leg 121 of each of the bails 102 to 110, inclusive, is providedwith an arcuately formed finger 126, the arcual surface of each of whichis of an incrementally shorter extent than that of the finger 126 of theadjacent lower order bail (FIG.

carriage frame.

4). The, lower portion of each finger 126 is beveled to provide achamfered surface which engages with a fiat surface provided within thecarriage frame 22 and serves as a limit stop for the corresponding bail,when rocked counter-clockwise (FIG. 3) to the inact've position thereof.The upper radially disposed edges of the arcuate fingers 126 of bails 2to 110, inclusive, are equiangularly displaced relative to each other,forming a helix circumferentially about the shaft 111.

The juxtapositioning of the tens-transfer bails 1112 to 110, inclusive,on shaft 111 is maintained by means of clips, or collars, 131 (FIGS. 5and 6) so that axial translation of the shaft 111 will effect asimultaneous adjustment laterally into either. of two positions foradditive, or subtractive, registrations, as will be describedhereinafter. In the conditon stated above, wherein the highest inboardorder dial 23. and all higher outboard order; dials register 0, axialtranslation of the shaft 111 to the right, to the subtractive positionshown in FIG. 6, positions the actuating finger 126 of each bail forentry into the notch 120 in the corresponding disk 118 upon clockwiserocking movement of the bails (FIGS. 3 and 4).

In the normally inactive position of the bails, the radial edge of thefinger 126 of bail 102 lies immediately beneath the lower face of thecorresponding disk 116. whereas the angular disposition of the radialedge of the finger 126 of each higher order bail relative to thecorresponding disk 118 is incrementally greater than that of theadjacent lower order bail. In recalling the correlation between thejuxtapositioned bails 102 to 1141, inclusive, it becomes apparent that acounter-clockwise rocking movement of the bail 102, as viewed from theright in FIG. 6, will cause a smilar rocking movement to be impartedsimultaneously to all higher order bails. Due to the equiangulardisplacement of the radial edges of the fingers 126 relative to eachother, it also becomes apparent that the finger 126 of bail 162 willenter the notch 120 in the disk 118 associated with the twelfth orderdial 23, followed by the entry, seriatrn, of the fingers 126 of thesucceeding higher order bails into the notch 120 of the disk 118associated with the corresponding higher order dials .23. i

shifted pos'tion and that the shaft 111 and the bails thereon are in theaxially translated leftmost, or additive, position, the actuatingfingers 126 of the bails, when rocked, will engage in the notch 1211 ofthe corresponding disks.

Referring now to FIG. 4, each of the legs 122 of the bails 102 to 109,inclusive, is provided with an angularly extended actuat'ng arm 127, allof which aims are in registry lengthwise of the shaft when the bails arein the inactive position shown. To resiliently maintain the ba'ls in theinactive position, the leg 122 of bail 110 carries a laterally extendedpin 132 which supports one end of a spring 133, the other end of whichis secured on the Spring 133 normally urges bail 11thcounter-clockwisetFlGS. 3 and 4) and, by virtue of the overlappingrelationship of the lug 124 on each higher ordinal bail with the ear 125on the adjacent lower order wiseto the inactive position.

As stated above, the sign character of incremental transfers into theoutboard order dials 23 is determined by the axially adjusted positionof the bail shaft 111. To permit the endwise adjustment of the shaftlll,the dependingarm of each bracket'112 and 113 supporting the respectiveends of the shaftiis positioned intermediate the legs 1 21 and122 ofthe. respective bails 111i and 162. lu-'- orderto control the.lateraladjustment of the bails 10 102 to 110, inclusive, relative tothe corresponding disks 118, the left end of shaft 111 is jouinalled inthe vertically disposed arm of a bracket 134 secured on the horizontallyextended leg of a setting slide 135 having a substantially L-shapedcross-section. As seen in FIGS. 3 and 5, setting slide 135 is mountedfor endwise movement on the lower forward portion of the carriage frame22 by pin-and-slot connections 137 and carries a series of dependinglugs 136 spaced in accordance with the ordinal arrangement of the dials23. The slide 135, and therefore shaft 111 and tens-transfer bails 1&2to 110, inclusive, are resiliently maintained in either the subtractiveposition shown in FIG, 5, or the opposed, or leftmost, additiveposition. For this purpose, a three-armed lever 140 is pivotally mountedon a stud 141 carried on carriage frame 22. At its extremity, thedepending arm .142 of lever 140 is provided with a bifurcation engaginga pin 143 on the left end of setting slide 135. A pin 1 on the free endof the second, or intermediate, arm 1 36 of three-armed lever 140 isprovided with an annular groove in which one end loop of asubstantiallly circular torsion spring 147 is engaged, the other, oroffset, loop of spring 147 engaging in an annular groove of a pin 148 oncarriage frame 22. Upon passage of the pin 144 below center, as seen inFIG. 5, spring 147 retains the third, or upwardly, extended arm 1 19 inengagement with a limit stop pin in the form of the head of a bolt 151.

Conversely, upon movement of the slide 135 to the left, to the additiveposition thereof, lever 140 is rocked clockwise to a position determinedby the engagement of the arm 149 with the head of bolt 152, similar tothe limit stop 151, wherein slide 135 is retained by spring 147.

As explained hereinbefore, and as conventional with machines of the typedescribed, upon initiation of a 1nchine operation, the sign character ofregistration in the register dials 23 is selectively controlled by anadjustment of the plus-minus gate 32 (FIGS. 2 and 3). in addition tocontrolling the sign character of registrations into the inboard orderdials 23, the adjustment of the plus-minus gate 32 also serves to effecta similar adjustment of the setting slide 135 to control the signcharacter of registrations of a transferred increment into the outboardorder dials. The ordinally arranged lugs 136, one for each outbail, eachof the bails is likewise urged counter-clock board order of theregister, extend downwardly from the forward edge of the horizontallydisposed portion of the slide and parallel to the vertical portionthereof, pro viding a channel within which the vertical offset end of anupright lever arm 156 is normally disposed. Lever arm 156 is secured ona hub 157 rockably and slidably mounted on a shaft 153 which issupported at its rearward end in a bracket 159 and at its forward end ina bracket 161. The brackets159 and 161 are secured on side frame member13 by respective screws 162 and 163 and serve to retain shaft 158 in aplane parallel to frame member 13. A lever arm 164, similar to arm 156,is carried by 'a hub 166 rockably mounted on a reduced diametral portionof hub 157 in a manner such that each lever arm 156 and 164 may berocked independently of the other, but are slidable as a unit on shaft158.

The upper end portion of the lever arm 16% is offset oppositely to thatof the lever arm 156 (FIGS. 3 and 5) and is formed inwardly toward, andis spaced from, the offset end of lever arm 156 for oscillation relativeto each other in' parallel planes. The spacing'between the planes ofoscillation of the respective offset ends of levers 156 and 164 issufiicient only to permit the passage of the lugs 136 therebetween uponshifting movement of the carriage.

At its extremity each of the lever arms 156 and 164 is engage theadjacent lug 136 in one adjusted position of the slide 135 and the otherear will engage the adjacent lug 136 in the other position of the slide135 following the lateral movement of the arms 156 and 164.

Referring now to FIGS. 3 and 5, the setting slide 135 is shown in itssubtractive position wherein a forward axial movement of the arms 156and 164 (to the right in FIG. 3) will position the ear of the arm 156for engagement with the adjacent lug 136. Similarly, if the slide 135 isin its additive adjusted position (to the left in FIG. the adjacent lug136 will be positioned for engagement by the ear of the arm 164following a rearward axial movement of the arms 156 and 164 (to the leftin FIG. 3). A subsequent scissorlike oscillation of arms 156 and 164will render either arm 156 operative to move the slide 135 from thesubtractive to the additive position, or arm 164 operative to move theslide from the additive to the subtractive position shown in PEG. 5.

As stated hereinbefore, the sign character of registration in theinboard order dials 23 of the register is determined, upon initiation ofan operation or during the progress of a plural order operation, by theadjustment of the plus-minus gate 32. Similarly, the sign character ofregistration in the outboard order dials 23 is determined by theadjustment of the setting slide 135 under the control of the oscillatinglever arms 156 and 164. In order to ensure registrations of like signcharacter in both the inboard and outboard order dials 23, a bellcrank167 (HG. 3) is provided, pivoted at 163 on side frame member 13. Alateral projection is formed at a right angle to the upper extremity ofthe upright arm 169 of bellcrank 167 and pivotally supports a roller171, adjacent the underside thereof, positioned diametrically betweenlever arms 156 and 164. The other arm 170 of bellcrank 167 carries a pin172 engaged in a bifurcation in the free end of an arm 173 secured onthe plus-minus gate shaft 34. it, therefore, becomes apparent that upona counter-clockwise rocking movement of the shaft 34 and plus-minus gate32 to engage the gears 28 with the corresponding dial shaft gears 24 foran additive registration, arm 173 imparts a clockwise rocking movementto the bellcrank 167, thereby moving the ear at the extremity of thelever arm 156 into its active position relative to the adjacent lug 136on slide 135. In a like manner, a clockwise rocking movement of theshaft 34 and plus-minus gate 32 to condition the machine forsubtraction, effects a counterclockwise rocking movement of thebellcrank 167 to actively position the ear at the extremity of lever arm164 relative to the adjacent lug 136.

Following the lateral adjustment of the lever arms 156 and 164, meansbecome effective to impart an oscillatory motion to the arms to enable acorrect adjustment of the setting slide 135. For this purpose, a bail176 (FIGS. 3 and 5) is rockably mounted at its one end on shaft 158 andat its other end in an annular groove in a hub 177 of a bellcrank 178,also rockably mounted on shaft 158. One arm 179 of bail 176 extendsupwardly, having an elongated pin 181 secured thereon engaging in avertically disposed slot in the lever arm 156, while the other arm 182of the bail 176 extends laterally through an aperture 183 in side framemember 13 for cooperation with a roller 184 carried on a disk 186 pinnedon the leftmost actuator shaft 46. It becomes apparent, therefore, thatwith each rotation of the disk 186 an oscillation of the additivecontrol lever arm 156 is effected. To control the oscillation of thesubtractive control lever arm 164, an upwardly extending arm 187 of abellcrank 178 carries an elongated pin 188 normally axially aligned withpin 181 and engaged in a vertically disposed slot in lever arm 164. Theother arm 189 of the bellcrank 178 extends laterally through theaperture 183 in frame member 13 and is normally angularly displaced fromarm 182 of the bail 176 for cooperation with a roller 191 on disk 186.The respective arms 189 and 182 lie in a plane adjacent opposite sidesof the disk 186 and normally rest against the hub of the disk extendingbeyond each side thereof. Arms 189 and 182 are resiliently maintained inengagement with the respective hub extensions of the disk 186 by meansof a torsion spring 192 coiled counter-clockwise (FIG. 5) about the hub177 of bellcrank 178 between the bellcrank 178 and arm 182, having itsone end overlapping a pin 193 on arm 182 and its other end underlying apin 194 on arm 189. Rollers 191 and 194, respectively, are carried onopposite sides of the disk 186 and are angularly displaced relative toeach other, so that during the first part of each cycle of rotation ofdisk 186, each roller 104 and 191 engages the respective arms 182 and189 to effect a simultaneous oscillation of lever arms 156 and 164,respectively, in opposite directions.

Subsequent to the oscillation of the lever arms 156 and 164 for theselective adjustment of the setting slide and the additive orsubtractive positioning of the tenstransfer bails 102 to 110, inclusive,relative to the corresponding disks 118, means are brought into play torock the bail associated with the highest inboard order dial 23 and eachof the bails to the left thereof, as viewed in FIG. 5. As explainedabove, the leg 122 of each of the bails 102 to 110, inclusive, isprovided with an actuating arm 127 for controlling the rocking movementof the corresponding bail and all higher order bails. In each ordinallyshifted position of the register carriage 20, the actuating arm 127 ofthe bail actively associated with the dial 23, which has become thehighest inboard order dial, lies in a position to the left of the sideframe member 13 (FIG. 5) for active cooperation with the rearwardlyextended offset end of a dipper arm 196 (FIG. 3). Arm 196 forms one armof a bellcrank 197 pivotally mounted at 198 on side frame member 13 andlies in a plane transversely of that of the actively positioned arm 127of the corresponding ball. The vertically disposed edge of a dependingarm 199 of bellcrank 197 is on the center line of the pivotal axis ofthe bellcrank and is maintained in engagement with a pin 201 on anupwardly extended arm 202 by means of a torsion spring 203. Arm 202 isintegrally mounted with a cam follower lever arm 204 on the respectiveends of a spacer sleeve (not shown) rockable about a stud 206 on sideframe member 13.

In the full-cycle position of the parts (FIG. 3), a roller 207 on onearm of the cam follower lever 204 is in engagement with the peripheralsurface of a cam 208 secured on the main drive shaft 50, whereby theextended end of the dipper arm 196 of bellcrank 197 is positioned abovethe plane of the laterally shiftable actuating arms 127 of thetens-transfer bails 102 to 110, inclusive. It will be recalled that themain drive shaft 50 is rotated once for each cycle of machine operation,including the operation of the shifting means to ordinally shift theregister carriage 20 transversely of the machine. After approximately220 counter-clockwise rotation of cam 208 (FIG. 3), the roller 207 onthe cam follower arm 204 will, under certain conditions to be describedhereinafter, be permitted to drop into an arcuate recess in theperiphery of the cam 204 under the influence of the torsion spring 203and the counter-clockwise rocking of the bellcrank 197. However, uponcyclic rotation of the cam 208 during a carriage shifting operation, thebellcrank 197 is retained in the inactive position shown in FIG. 3against the urgency of the torsion spring 203. For this purpose, an ear211 is formed at a right angle to the rearwardly extended arm of the camfollower lever 204 and normally underlies a square stud 212 on anupright arm 213 pivotally mounted on an extended pin 214 on the upperend of an arm 216 rockably mounted on a pin 217 on frame member 13.Thus, the roller 207 on cam follower 204 is prevented from dropping intothe arcuate recess in cam 208.

If a machine operation, other than a shifting operation, is initiated,i.e., an operation involving the adjustment of the plus-minus gate 32for positive or negative registrations in the register dials 23, theadjustment of 13" the gate 32 in the initial part of the cycle willeffectremoval of the square stud 212 from its engagement with the ear211 of cam follower lever arm 204. A link 218 is pivoted at its one endat 219 on the left-hand arm 33 supporting one end of the plus-minus gate32 and at its other end is pivotally mounted on the pin 214 on arm 216.Normally the square stud 212 is resiliently maintained in thecentralized position shown in FIG. 3 by opposed arms 221 and 222adjacently mounted for rocking movement on the pin 217 and spaced fromarm 213 by the interpositioning of the forward end of link 218. A spring223, secured at each end on an ear of the respective arms 221 and 222,normally urges the facing edges of the arms into engagement withdiametrically opposed surfaces of the pin 214 and a pin 224 secured onarm 213 intermediate the ends thereof. It can be seen, therefore, thatupon adjustment of the plus-minus gate 32 to engage either the plus gear28 or minus gear 29 with the corresponding dial shaft gear 24, the arm216 will likewise be rocked counter-clockwise, or clockwise, and thespring 223 will thereafter serve, through either arm 221 or 222,respectively, and pin' 224 to rock arm 213 similarly, thereby moving thestud 212 rearwardly or forwardly of ear 211 on lever 204.

Although the stud 212 is moved out of blocking position relative to theear 211,.the roller 207 of lever 204 will remain in engagement with theperipheral surface of the cam 208, thereby retaining the bellcrank 197in its inactive position for approximately 220 of. the cycle. Duringthis portion of the cycle, the rollers 191 and 184 on disk 186 becomeeffective to adjust the setting slide 135 in accordance with the signcharacter of registration in the register dials 23. Subsequent to theadjust ment of the setting slide 135, the torsion spring 203 rocksbellcrank 197, urging roller 207 into the recess in the periphery of camdisk 208. As it is rocked counterclockwise (FIG. 3), the extended endportion of the arm 196 of bellcrank 197 engages the actuating arm 127 ofthe tens-transfer bail associated with the highest inboard order dial23, rocking that bail and all bails to the left thereof in a clockwisedirection.

Assuming the condition given hereinbefore wherein the carriage 20 is inthe leftmost shifted position, the sign character setting slide 135 isin the adiusted subtractive position, as seen in FIG. 5, and the dials23 register 0. The arcuate actuator fingers 126 of each tens-transferbail 102 to 110, inclusive, will 'be actively aligned with the notches120 (FIG. 6) in the disk 118 on the corresponding dial shaft 21.Thereafter, as bellcrank 197 is rocked, under the influence of spring203, the arm 196 of the bellcrank rocks the actuator finger 126 of thetenstransfer bail 102 into the aligned notch 120 in the disk 118associated with the highest inboard order dial '23. Simultaneouslytherewith, the actuator finger 126 on each of the tens-transfer bails tothe left of the bail 102 will likewise be'rocked into the aligned notch120 in the corre sponding ordinal disk 118.

Following the rocking of'the actuator'finger126 of each of bails 102 to110, inclusiveinto active position relative to the disk 118 associatedwith the corresponding dial 23, the subtraction of l in any keyboardorder of the machine will cause the coordinal dial '23 to be rotatedfrom to 9, thereby initiating a tens-transfer, successively, in eachhigher inboard order dial'23. As

the highestinboard order dial 23 passes from 0 to t 9, the disk 118associated therewith causes a lateral position of the slide 135 is theadditive position, so that "if thefollowing'machine operation is'of anadditive sign tive position thereof.

character the positive setting lever 156 will be idly rocked. However;if the succeeding machine operation is of a subtractive sign character,the rocking of the negative setting lever 164 will move the settingslide and tens-transfer bails-102 to 110, inclusive, to the subtrac-Similarly, if the setting slide 135 is left in the subtractive adjustedposition shown in FIG. 5, and the ensuing machine operation is of anadditive sign character, the positive setting lever 156 will becomeeffective to move the slide 135 to its lefthand position.

For a condition wherein the carriage 20 and the setting slide arepositioned as shown in FIG. 5, but the sixteenth order dial 23, Le, thefourth outboard order dial, registers a value other than 0, the arcuateactuator finger 126 of the tens-transfer bails 102 to 105, inclusive,will be rocked into the aligned notch in the disk 118 associated withthe corresponding dial 23, whereas the radially disposed edge of theactuator finger 126 of bail 106 will enter the aligned radially disposedrecess 119 in the disk 118 of the sixteenth order dial 23. Inasmuch asthe radially disposed edges of the actuator fingers 126 form a helixcircumferentially about shaft 111, the entry of the actuator 126 of bail106 into a recess of the corresponding disk 118 precludes the activepositioning of the actuators 126 of the higher ordinal bails 107 to 110,inclusive. Consequently, as the highest inboard order dial 23 passesfrom 0 to 9 upon the subtraction of 1, the thirteenth, fourteenth andfifteenth order dials 23 will be simultaneously rotated to 9, while theregistration in the sixteenth dial will be decreased by 1. It becomesapparent that if, during a subtractive operation, the highest inboardorder dial 23 or any of the higher outboard order dials 23 register avalue other than 0, the actuator 126 of the corresponding bails willenter the aligned recess 119 in the associated dial disk 118, while thebail to the left of the actively positioned bail will remain inactive.In a similar manner, the actuator finger 126 of all the tens-transferbails to the left of the highest ordinal actively positioned bail willremain inactive during an additive operation, if the actively positionedbail is engaged in an aligned recess 119 in the disk 118 associated withthe highest order dial registering a value other than 9.

Upon shifting movement of the carriage 20, to the right from theposition shown in FIG. 5, each of the outboard order dials 23 isordinally shifted inboard of the machine and thereafter comes under thecontrol of the conventional tens-transfer mechanism. It is, therefore,neces sary that each tens-transfer bail 102 to 110, inclusive, bedisabled as the associated dial is ordinally shifted to the 'right andbecomes the next to the highest inboard order dial. For this purpose, ablocking member 225 is secured on the inside of the sideframe member 13(FIGS. 3 and 5), having its upwardly extended end formed at a rightanglethereto and positioned in a plane parallel to the plane of shiftingmovement of the normally inactively positioned actuating arm 127 of thetens-transfer bails 102 to 109, inclusive. As each tens-transfer bail isshifted inboard of the machine, the actuating arm 127 thereof moves to aposition overlying the blocking member 225 which prevents rockingmovement of the corresponding bail and, because of the overlappingarrangement of the ear 126 of a lower ordinal bail with the car 124 ofthe adjacent higher order bail, each'bail to the right of the positivelyblocked bail is also disabled.

As explained hereinbefore, upon adjustment of the plus-minus gate 32 foran additive or subtractive operation, the square stud 212 is moved tothe left or right of the ear 211 on lever 204 (FIG. 3), therebypermitting operation of the bellcrank 197 and. arm 196. Afterapproximately 220 of each cycle, the roller 207 on lever 204 drops intothe recess in cam 208 and the ear 211 rocks to a position to the rightor left of the square stud 212. The plus-minus gate 32 remains in itsadjusted position until near the end of the cycle of machine operation,whereupon it is restored in a well-known manner to the neutral positionshown in FIG. 3. Substantially simultaneously, with the restoring of theplus-minus gate 32, the cam 208 rocks the lever 204 counter-clockwise,raising the dipper arm 196 to its inactive position and moving the ear211 to its normal position below the square stud 212.
